This invention relates to a novel andimproved reverse-gear swingingwringer mechanism for washing machines and the l1ke and consists of thematters hereinafter d escribed and more particularly pointed out- 1n theappended claims.'

The object of the invention is to provide a simple, economical andeiiicient reverse-gear swinging wringer mechanism capable of being swungto any one of a predetermmed number of positions in which the wringerisv myspecication.

In thedrawings Figure 1 is a view representing a vertical centralsection through 'the improved swinging wringer mechanism, with'thereverse gearing in neutral position and with the' control arm in thatposition which it occuples 4when the wringer isin one of itspredetermined positions and is locked againstswinging movement.

Figure 7 is a top plan view of a notched collar or fia-nge on thetubular post supporting the gearing, -the notches in said collarcorresponding to the Vseveral predetermined positions of the wringer.

Referring n ow to that embodiment of the invention illustrated in thedrawings, as designed for use with a power driven washing machine ofanygfamiliar typen- 10 indicates the usual tubular bearing' standardadapted to be supported upon and to extend vertically alongside a powerwashing machine'tub 10a, containing'and providing bearing for a powerdriven vertical shaft 11. (See Figs. 1 and 4.) said standardjhas ahorlzontal radial flange or collar 12 which presents a base or support.for theswinging wringer mechanism indicated, as a whole by the numeral13.

14: indicates a housing having a flat annular-base 15 resting upon theflange 12,

At its upper end with a depending Itubular post 16 which engages and hasrotatable bearing'in the tubular standard10. A vertical shaft 17 hasbearing in the tubular post 16 and depends therebelow to be cou led tothe power driven operating shaft 11 y a diametric pin and slotconnection -18 in 'a familiar manner. Said shaft 17 extends verticallythrough the Vhousing 14, which provides for it a top bear- .p Onsaidshaft are assembled the two' 20 and' 21, with'the movable h ycollar 22between them for 'ecting the one or other to -both reverse gearsengaging operating gear 23 which A'gen1-.all Vin a well known gearsvoperativ the" shaft `1 the p efwrnger 24. .,"It contains ahorizental;-bushing24et in which bears thel hollow-hub-23'L4 of theintermediate gear23. Said hollow hub is'designed to receive the endcontains a polygonal lsocket 25 for locking vsaid wringer shaft tothesaid intermediate Y 4racket-which directly supv' of theT driven shaft 24jofthe wringer and p' tudinal movement inthe housing 14 in any familiarmanner, as by a pin 26 taking through the top bearing 19 and engaging anannular groove 27 on the shaft. Obviously the housing 14 with itsenclosed gearing, the

shaft 17 and the attached wringer, may be 28 against any movement in aplane at right angles to said shaft 28 so that it may rock the shaft toshift the clutch collar. But said control arm is capable when inQ'onepositiony of a swinging movement in the plane of the shaft 28 away fromthe housing-as from the vertical position shown in Figure 1, to aposition inclined away from the housing, as

shown in Figure 2. Said movement is made possible by reasonofa pin andslot connection of the arm 31' to-the shaft 28, las indicated at 33.

The housing, adjacent the arm 31, is provided with a boss 32, whichabuts' against the arm 31 in a semi-circular arc above the horizontalaxis of the shaft 28, but is cut away below said axis, as indicated at32a (Figs. 1 and 2) topermit the arm 31, when in vertical position, tobe swung from the vertical position shown in Figure 1 to the positioninclined away from the housing, shown in Figure 2.` In these positionsof the 'arm 31, the'shaft 28 and its eccentric pin 29 are in position tohold the clutch collar 22 in neutral position. In any other position ofthe arm 31, as when it has been swung into horizontal position,illustrated in Figure 3. to rock the shaft 28 and shift said clutchcolla-r into operative engagement with one of the reverse gears 20, 21,the boss 32 will block any swinging movement of the arm 31 on its pivotpin 33.

In the edge of thesupporting flange 12 of the vertical standard 10,there are provided a plurality of notches 34, the number of said notchesdepending upon the number of positions which the swinging wrmger isdesigned to occupy, each notch corresponding to 'one of said positions.In the vertical plane of theswinging movement of the arm 31 away .fromthe housing and immediately'below the shaft 28 on a horizontal pin 35 ismounted a spring-controlled pivotedtrigger 36. Said trigger is suitablyplaced in a vertical slot provided by parallel spaced'iribs 37projecting from the housing, and as shown, depending from the boss 32.Insaid ribs the pin 35, placed intermediate the ends of the trigger, isfixed. The bottom end of the trigger 36 extends into the plane of theflange 12 of the standard for engagement with one of the notches 34therein. Said trigger is held in engagement with the said i'ange 12bymeans of aball 38 and spring 38 mounted in a downwardly and outwardlyinclined recessv39 in the rock shaft 28, with the ball in engagementwith the upper end of the trigger. lVhen the housing 14 with theattached wringer 24c is swung on its vertical axis, as by the rotationof the post 16 in the standard 10 to bring the trigger 36 opposite oneof said notches 34, said trigger will be forced by the spring into saidnotch and thus lock the housing Y against further rotative movement.

Thecontrol arm 31 has a finger 40 which depends below the rock shaft 28to the horizontal level of the upper end of the trigger 36 and above itspivot pin 35, when said arm is in its vertical position Correspondingwith the neutral position ofthe clutch collar 22 lVhen in that position,and when in that position only, the arm 31 may be swung on its pivot 33away from the housing,-that is to say, from the position shown in Figure1 to the position shown in Figure 2. In this movement the finger 41 willdepress the upper end of the trigger (against the action of the spring38a) and lift the bottom end of the trigger from its engagement with thenotch 34. This releases the housing and, with the control arm in theposition shown in Figure 2, the housing may be swung by said arm 31 tobring the wringer to afposition corresponding to another notch 34,whereupon the arm 31 will be shifted back to vertical position,releasing the trigger which is forced by the spring 38a intoengagementgwith said notch. This locks the housing in the new position.

At any position of the wringer intermediate the several positionscorresponding to the several notches 34 in the flange 12, the upper endof the trigger 36 will engage in the open end of the recess 39, asillustrated in l control arm is incapable of shifting the clutch collarto operatively connect either of the reverse gears to the shaft 17 foractuating the wringer shaft. When the housing and wringer are brought toposition so that the trigger is oppositev one of the notches 34, theball and spring will force the trigger into said notch, thereby swingingthe upper end of the trigger from its engagement in the open end of therecess 39 and releasing the rock-shaft. The control arm 31 may then beswung in a ver- -tical plane (at right angles to the rock shaft) toshift the clutch collar. -A depression 50 in the bearing fori the .rockshaft, is located to be engaged by the ball 38 when the rock shaft 28 isin neutral position, thus providing a yielding lock for said shaft inthatiposil tion.

From the foregoing description, it will be obvious that the singlecontrol arm 31 is operative both for reversing the gearingand forswinging the wringer; that said arm may onlysu'ing the wringer when thegearing is in neutral position; and that said arm may only reverse thegearing when the wringer is in one of its predetermined positions.
